Refrigerant manufacturer Honeywell, which co-developed R1234yf with Chemours, has filed an application with the United States Environmental Protection Agency (EPA) seeking approval for the use of YF as a retrofit refrigerant in R134a systems. This step, previously considered unlikely due to YF’s A2L mild flammability rating, was motivated by growing concern about the availability and Continue reading R1234yf retrofits coming after all?
German brand sharing CO2 tech to accelerate automotive adoption After years of resistance, Mercedes-Benz parent company Daimler has finally decided to adopt R1234yf in some models, but only as a stepping-stone towards the range-wide rollout of cars with air conditioning systems using CO2 refrigerant (R744). The first R744-equipped models will be the high-end S-Class and Continue reading Mercedes-Benz adopts R1234yf as CO2 stepping stone
There may be media-fuelled public resistance to R1234yf history in Germany – not to mention the refusal by Mercedes-Benz to adopt it and Volkswagen Group’s commitment to CO2 as a refrigerant – but government figures reveal that there are already half a million cars on German roads with the new gas coursing through their air Continue reading 500,000 cars using R1234yf in Germany
Rodney Smith from CoolCar Air-Conditioning Centre Hamilton conducted a mini survey on New Zealand-new cars displayed at the New Zealand Agricultural Fieldays near Hamilton in June 2015. He wanted to get a feel for what refrigerant was in the air-conditioning of the latest cars and talk to the sales staff on the stands. A similar review Continue reading Snapshot of NZ new car AC refrigerant
The Abbott Government’s proposal to relax new vehicle importation laws and enable personal imports of new cars could accelerate the uptake of R1234yf in Australia if the legislation passes. On some production lines, only models destined for countries where low global warming potential refrigerants are either compulsory or receive fuel efficiency credits are fitted with Continue reading New car import laws could accelerate R1234yf growth in Australia
Growing use of flammable refrigerants like R1234yf has prompted the United States Air Conditioning, Heating and Refrigeration Institute (AHRI) to establish a subcommittee that will review safety issues related to mildly flammable ‘A2L’ class substances. In addition to representation from the refrigeration and air conditioning sector, the safety subcommittee will comprise flammability experts and people Continue reading More A2L flammable safety studies
